SANITARY FONT ron POULTRY.

Ap lication filed January 4,1927; "Serial No. 158,252.

This invention relates to "devices for dispensing feed to poultry andmore particu tion without spill or wasteful overflow of itscontents. v Iv Another ob ect is the provisionof a font in which the feed unagazineisautomatically positioned and supported relative tothe teed'trough'through the medium otcam and wiper devices. I

A further object is .to provide a,poultry .iontihaving an adjustableguard unctional to limit access to the feed trough or pan and therebyprevent the entry of young chicks.

A still further object is toturn shithe tont with aremovableroosting-preventer, so that the filling ofthe feed magazine maybe more expeditiously efiectedr v TWith the above general Ob ects inview my invention consists in the features of construction combinationand arrangement of parts hereinafter described, illustratedby'theacconipanying drawings, and specifically "dcfined as .tosubject-matter and scope in the subjoined claims.

.Iteterring, more particularly to Figs. :I-Jlll inclusive, theieedtrough orpan 3 is of conventional sheet metal construction with -anupwardly extending annular flange 4, "Finished" oil by a circumferentialbead 5.

, {The feed magazine '12consistsofa cylindr1cal1body portion 13 ofpredetermined capacity and adiaineterclosely approximating that of thespreader 6, at its base or junction with the .pan 3. The magazine 12 1sclosed-in at the upper end byn flat'top le jw ith provision of aple'rilnetrical flange 15, i'unc, tional to protect said top from groundcontact and damage when themagazine is in 'verteol forffillingpurposesor cleaning." The perimetricalflange '15also affords an annu larretainer in which the conical roostingpreventer or removable top16863115, when the dev ce is insuse.

I This roosting-preventer or removable 'conetop "16 s hollow and madesheet metal with a surroundinginternal bead 1'7to reinforce the sanieyaswell as to eliminate anyeziposed sheet metal edges. I

Slidably fitting the feedmagazine 12 is a truncate gu'ardor conical hood18 of sheet metal having Jeri-metrical beading 19; 20 at the upper andlower edges,- respectively.

Thisguard or hood 18 is adapted forsecure :retention: at therequiredelevationyrelative to the feed pan 3, by 'nieans'ofa'winge'dsetscrew 2'1, threadedly engaging an aperture in "thevertical p0rtion'22ofanianglemeniber 23, riveted or otherwise'immova'bly attached to saidguard or "hood As will be apparent, 'inore particularly from Fig. 11,the winged set-'screWQl'engage-s the exteriorsurtace of the nagazine '12in'clamping the guard or hood '18 at the required height.

The means eii ectiv'e'toproperly center and support the magazinel2relative to thepan 3 compriseoutstandingradial studs 24 convenientlyintegral with meni'bers25 attached 1thepan'3,w I l l; or mg d studs intwoperatweem its basalbe" d :27: so that said =-niagazine inay gagementwith the cam devices 8, as later on explained. Incidentally, the camdevices 8 are provided with apertured end pieces 28 for the reception ofrivets whereby they are rigidly secured in the pan 3, as will be wellunderstood without further description ant these end pieces are of adepth or thickness to standon the perimetric flange 15. The

feed trough or pan 3 is next removed in an.

obvious manner. The magazine 12 is then filledfor example to the levelof the studs 24, and the feed trough or pan 3 replaced by a reverseoperation to that just described;

whereupon said ma azine and pan are inverted and the former manipulatedby turning untilthc studs 24 seat on the rests 11as shown in Figs. I andII-'-with determination of the liquid level 29 (Fig. II) in said pan.The roosting-preventer 16 is replaced, when the fontis ready for use,after the truncate guard or conical hood 18 has been adjusted as setforth-to the proper height for the size of chicks being fed. It will bereadily understood that the liquid food M is gradual- .ly deflectedoutwards by the spreader 6 into-- and maintained at a constant levelin-the pan 3 under the lower edge of the cylindrical body 13, withoutwasteor overflow-over the beaded edge'5 of said pan. In some instances Imay provide the cam devices 8 with a series of rest-s 11 and inclinedfaces 10- Fig. IV thereby affording provision to vary the level 29 ofthe food M in the pan 3, as will be well understood without furtherexplanation. herein.

Incidentally the truncate guard 18 is rai'sedas the chicks grow-byincreasing the interspace between the same and the beaded edge 5 of thepan 3; while it may be lowered down thereon when it is desired to ceasefeeding, and thereby protect any food remaining in the annular feedingspace from contamination, or the ravages of rodents and vermin.

From the foregoing my invention will be understood as fully justifyingall the objects and advantages set forth, while it is equally apparentthat detail structural changes may be effected without departing fromthe spirit of said invention as tersely defined in the following claims.

Having thus described my invention I claim:

1. A poultry font, comprising a feed pan having a conical spreader.concentric with its base, cam devices about the lower part of saidfeeder, and a feed-magazine having radially directed elements forco-operative engage ment with the cam devices in centering andsupporting said feed magazine in the feed 2. A- poultry font comprlsinga feed pan having a conical spreader concentric with its base,uni-directional cam devices about the lower end of said spreader havingrest portions, and a feed'magazine having radially directed projectionsadapted to co-operate with the cam devices aforesaid in positivelypositioning and supporting the magazine in the pan, respectively.

3. A poultry font comprising a feed pan having a conical spreaderconcentric'with its base, uni-directional arcuate cam devices about thelower end of said spreader having stepped rest portions, and a feedmagazine having radially directed elementsadapted to co-operate with thecam devices inpositively positioning and supporting the magazine. atvaried elevations relative to the pan,

4. A poultry font comprising a feed pan having a conical spreaderconcentric with its base, uni-directional cam devices about the lowerend of said spreader having rest por tions, a feed magazine withradially directed studs adapted to co-operate with the cam devices inpositively positioning and supporting the magazine at variedelevationsrelative to co-operate with the inclined faces and restsaforesaid in centering and supporting the magazine in the pan, aremovable roostingpreventer fitting a peripheral. extension flange atthe top of the magazine, and a truncate guard adjustable relative to thefeedpan by means of a clamp screw.

6. In a poultry font of the type described, a feed pan, a feed magazineseating in said pan; cam, means about the feed pan, and projectionsabout the feed magazine.co-operative with the cam means, jointlyfunctional to effectively center the feed magazine relative to the panwith capacity for inversion of the font and rigid support of saidnaagazine without spill or wasteful overflowof its content so long asthe lower edge ofthe magazine locates below the upper edge-of the feedpan.

7. In a poultry font comprising a bottom pan, a magazine having radiallyprojecting stops and adapted to beinverted aX'ially'in the pan withprovision of acircumferential feed well and retainment of its contentthrough sealing at its lower edge in the well,- and stepped cam devicesco-operative withthe aforesaid stops by partial rotation of the magazineto vary the elevation of its lower edge relative to the pan and therebyincrease or decrease the depth of the feed in said Well.

8. In a poultry font comprising a feed pan, an invertable containeradapted for concentricseating in the pan with provision of a seal aboutits lower edge, cam devices in the feed pan, and projections about thecontainerco-operative with said cams to vary the elevation of saidcontainer in controlling the depth 7 of the feed in the pan exterior tothe container. f

In testimony whereof, I have hereunto signed my name at Philadelphia,Pennsylvania, this 30th day of December, 1926.
